**Calculating the average of a group of numbers is quite simple: you sum them all up and divide by how many numbers you have. For example, the average of the number 1, 2, 3, 4 and 5 is: 1 + 2 + 3 + 4 + 5 divided by 5, because there are 5 numbers. **

You could do this in Excel by typing `=SUM(1,2,3,4,5)/5`

into a cell. But there is an easier way. You can simply use the AVERAGE function. It looks something like this:

=AVERAGE(1, 2, 3, 4, 5)

And, as with the SUM function, you can use references to cells, like **A1** or **C4** in there instead of numbers.

Use the AVERAGE function in cell **A7 **to calculate the average of the numbers in cells **A1 **through **A5**.

**Note:** You have probably noticed that both of these functions are written in all-caps. That’s just the way function names in Excel are. So it may look like I’m screaming SUM at you, but that’s just how it is written ðŸ˜‰
